TEMPLE SELVAGE TRIMMER.

Application filed July 30, 1923. sci-m1 No. 654,528.

To all'wkom it may concem:

Be it known that I, EMERY OoRMIER, a subject of the King of Great Britain, residing at Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Temple Selvage Trimmers, of which the following is a specification.

This invention relates to improvements in box looms, and more particularly to the provision in that type of loom of a temple'selvage trimmer at the box end of the loom.

In Weaving cloth on a box loom the weft.

or filling thread running to the shuttle carrying the bobbin of the color not in use, is drawn forwardly b the advancing cloth and lies along the e ge of the selvage while the weaving is continued by filling threads of another color from the other shuttle or shuttles according as there are two or more colors in the cloth. The formation of this extra and undesirable thread parallel to the selvage edge continues until the time'comes to again use the idle shuttle, when this thread is again picked through the shed.

This forms extra loops of the yarn forming the weft thread alternating in color, when the cloth is being woven from two colors only, all along the selvage at the box end of the loom. If more than two colors are used the threads will overlap and form loops of two, or more threads. These loops are se-' cured at each end to the cloth and heretofore they have been drawn so tight against the selvage, by the operation of the shuttle and the beat up of the lay, that great difficulty has been experienced in trimming them from the selvage. So far as I am aware the expensive hand trimming has been the universal commercial practice inthe mill, prior to my invention.

Trimming these selva e 100 s of the varicolored weft threads by and is not onlyexpensive but is a slow and tedious operation. Accordingly the object of the present invenvtion is to provide a trimmer, o erated by the loom itself, for severing these oops of extra thread at the box end of the selvage whlle the cloth is being woven in the loom. I believe that I am the first to provide a boxloom with an automatically operated selvage trimmer which will effectually sever the filling thread loops from the selvage without in uring the cloth.

' While the ortions of the weft threads left attached to t e selvage at the box end of the because most frequently attached to the selvage by both ends, it will be understood that when weaving cloth in stripes from two or more colors the formation of complete loops from the inactive filling threads depends upon the character or design of the cloth being woven. The inactive filling threads'may, according to the nature of the design being woven and the positions of the temple and the trimmer relative to the characteristic features of said design, be attached to the selvage at one end only at the time the automatic trimmer becomes operative. In its broader aspects the object of the present invention is to provide means, in a box loom for severing all surplus filling threads, of whatever nature they may be, from the box end selvage before the cloth leaves the loom. The term loops in the appended claims should be so construed wherevnot otherwise limited.

To the accomplishment of this object and i such others as may hereinafter appear, as will readlly be understood by those skilled in the art, the invention comprises the featemple at the box end of the loom at each beat up of the lay, a portion of a two color blanket being shown in the process of being woven, Y Fig. 2 is a view, in front elevation, of the selvagetrimmer as shown by Fig. 1,

' Fig. 3 is a cross-sectional view, in elevation, of the operating mechanism taken on the dot and dash line of Fig. 2 and looking in the dlrection of the arrows 3-3 thereon,

Fig.4 is a cross-sectional view, in elevation, of the trimming mechanism taken on the dot and dash line of Fig. 2 and looking in the direction of the arrows 4-4 thereon, and

Fig. 5 is a diagrammatic view, in plan, of the outer end of the temple head illustrating the manner of forming a slack loop from the filling thread leading to the idle shuttle when that shuttle is again brought into position for the first pick through the shed upon a change of color.

The invention, as has already been pointed out, is for use on a box loom, of any wellknown type, for example a Crompton & Knowles box loom, and is applied to the temple at the box end of such a loom, because the filling thread loops to be trimmed by the mechanism of this invention are formed only on the selvage at the box end. Since the invention is not concerned with a particular form or construction of loom no detailed description or illustration of the loom itself is necessary.

Looms are universally provided with a temple at each side, the main function of which is tomaintain the .cloth forward of the fell in a stretched condition of uniform width. In the embodiment of the invention illustrated in the drawings the temple selvage trimmer is combined with the box end temple 10 (Fig. 1), the temple stand 12 of which is adjustably mounted on the breast beam of the loom by bolts threaded in the customary manner into the upright portion 14 of the. usual supporting bracket 15, which in turn is bolted to the breast beam. The temple thus projects rearwardly from the breast beam and its shank 16 slides in the stand 12 and is yieldingly normally projected rearwardly by a spring (not shown) in the temple stand. This shank 16 carries at its-rearward end the temple head 10. Within the temple head, which is slotted to permit the passage of the cloth, there is provided the usual in pointed or porcupine temple roll (hidden from view 1n Fig. 1). At each beat up of the lay thefront of the lay strikes against a depending heel 18 (Fig. 2) forcingthe temple forwardly over the cloth. This latter feature is referred to because it is mounted on the temple head and is conveniently utilized in the present invention for operating the novel selvage trimming mechanism.

With this preliminary description .of the pertinent features of the loom I may now pass to a description of the preferred form of construction of the present invention.

Secured to the lower face of the temple stand 12 is a table 20 which projects inward and lies in front of the temple head 10. This table is slotted at 22 (Figs. 1 and 4), for the reception of the vertically arranged trimming knives, and at the inner edge of said slot there is provided a vertical bracket or stand 24 having a right-angular extension 26 running parallel to the temple head, beneath which and over the table 20 the cloth travels. The inner wall 25 (Fig. 2) of the stand 24 acts as a gage for the selvage edge of the cloth. The cloth is held down upon the table 20 by means of a resser foot which comprises a plate 28 gui ed for vertical movement on the stand 24 (see Fig.

lustrated in Fig. 1, are supported in a ver-' tical slot 36 in the outer face of the stand 24. These comprise a fixed knife 38 seated in the bottom of the slot and a movable knife 40, also in the slot and overlying the fixed knife. The fixed knife 38 is slotted horizontally at its rear edge, just above the table 20 (Fig. 4), and provides an upwardly directed cutting blade 42 in the plane of the surface of the table. The movable knife 40 has an oblique lower edge which forms a downwardly directed cutting blade 44. The knives are held in the slot 36 by a cover plate 46. When the knife 40 is reciprocated, by mechanism presently to be described, the blade 44 shears across the blade 42 at each downward stroke, thus severing any filling thread attached to the selvage which has been brought to a position between the blades by the advance of the cloth. The cuttingedges of the trimming knives are located about onesixteenth of an inch from the selvage gage 25 thus insuring a sufficiently close trimming of the selvage loops but without dama e to the selvage. It will be understood from Fig. 4 that the stand 24 is cut away behind the knives to permit a tracking of thel looped filling threads into position between the cutting blades when open, as the cloth is advanced past the knives.

The mechanism for operating the reciprocating knife 40 will now be described. The roximate actuator ior the knife 40 is a ell-crank 48 (Fig. 2), fulcrumed at 50 on the knife side of the stand 24, having its horizontal arm connected to the upper end of the knife bar by a pin and slot 52' and normally maintained raised by a suitably mounted spring 54. The limit of upward movement is determined by the en agement of the lower end of a vertical gui eslot in the knife bar with a bolt 56 (see Fig. 4).

A wear piece 'on the vertical arm of the bellcrank 48 is engaged by an arm 58 fixed on a rock-shaft 6O journaled in a bearing 61 at the forward edge of the table 20. When this shaft is rocked in a clockwise direction, viewing Fig. 4, the knife is depressed, a return being effected by the spring 54. The shaft 60 is rocked at each beat up of the lay by the mechanism shown in Fig. 3. The shaft carries a second fixed arm 62, substantially parallel to the arm 58, which underlies a rearwardly extending arm 64 loosely pivoted at its forward end on the temple stand and carrying a roll 66 at its mechanism described, rocks the shaft 60 and depresses the knife 40 causing its blade 44 to make a shear cut across the blade 42 of the fixed knife 38. As the lay swings rearwardly the temple head springs rearwardly and the movable cutting blade moves to open position. a

It is obvious that each filling thread selvage loop must be'provided with sufficient slack to enable it'to lie across the knife blades. Otherwise the knives could" not sever the thread. The manner in which this slack is formed is an extremely important feature of the invention and will be described in detail later. Assuming for the present that each loop is slack, as illustrated in Fig. 1, the means will now be descrlbed for opening up the loops-so that their ends attached to the selvage will be drawn out.- wardly and attain a position substantially normal to the selvage at the time they'pass between the knife blades.

extension 26. The lever 78 is pressed down The rear end of thehorizontal arm of the bell-crank 48 has a pin engaging in a slot (see Fig. 1) in the outer end of a lever 78 pivoted centrally on the rear face of the knife stand extension 26. The inner end of this lever has pivoted thereto a de ending pawl 80 adapted to engage the teet of a ratchet 82 rotatable on a'pm fitted in the face of said by a suitably mounted spring 84 engaging its inner end and the pawl is held to the'ratchet by a suitably connected coil spring 86. A look pawl 90 is pressed toward the ratchet by a spring 92. With this construction the ratchet is rotated one step, in a counterclockwise direction as seen in Fig. 1, at each upward movement of the knife 40. This rotation is utilized to actuate a 100 -spreader 94 in the followingmanner. e ratchet carries a crank pin 96 on which is pivoted a loop-spreader arm 98 the longitudinal movement of which is guided by a screw 100 entering the stand extension 26 through a slot 102 in the inner end of the arm. The outer end of the arm 98 carries a loop spreading foot 104: which may be of any suitable construction but is preferably formed of a plurality of independently yielding members, as clearly shown in Fig. 1. As the crank pin 96 traverses the lower ortion of its orbit of motion the loop sprea ing foot is advanced across the line of feed of the selvageof the cloth and the vertical position of the arm 98 is such, at this time, that the s reader feet engage" and rub across the tab e 20 which places =their springs under some tension.

Thus as the loops are advanced they are periodically engaged by the spreading foot 104 during three or four successix e advance steps thereof before the crank pin begins to rise and thus carry the foot upward and then rearward. This contact with the loops is sutlicient to open each loop to its fullest extent just before reaching the trimming mechamsm, and thus provide for an efficient trim- 'ming' operation by the shearing action of loop cutting knives 38 and 40. The loop '11:

being fed to the knives, in Fig. 1, is shown as having just been stretched by the loopsp'reader-which is rising from its operative loop spreading position.

The table adjacent the knives should be kept clear of the accumulation of thread ends and to this end a thiead end clearer-is provided. Theclearer is in the form of a rotary blade 110 which turns in the space between the knives and temple stand (see Fig. The two or more blades of the clearer are of such length that they sweep across the table 20, engaging and ejecting all the severed thread ends that do not fall through the slot 22. The clearer is carried on the inner end of a horizontal shaft 112 journaled in a bearing 114 on the top of the temple stand. Between the clearer and the journal is a ratchet 116 adapted to be engaged by a pawl 118 carried on the auxiliary slide 7 2. Thus the clearer is rotated, step by step, at each beat up of the lay. A coiled shaft spring 120 holds the clearer yieldingly in its bearing. As shown by Figs. 1 and 3 the pawl 118 is held loosely on the slide 72 to prevent breakage in case of jamming.

I will now describe the important feature of' providing slack in the selvage fillindicate blueor white threads, and the white loop'just produced is shown by anirregular dotted line where it lies hidden within the temple slot. The thread B runs from the rear edge of the last blue stripe woven to the shuttle which carries the blue thread bobbin, which we will assume is in the upper box, now raised above the picker bar.

The thread W runs to the shuttle which carries the white thread bobbin and is in the lower box, now.in position to be picked through the shed and weave a white stripe. At the succeeding beat ups of the lay in weaving the. white stripe the end of the blue thread B attached to the selvage is advanced with the cloth through the slot in the temple head 10 and, at the time the white stripe is completed, lies in approximately the position of the dotted line B in Fig. ,5,

that is, behind a hook 130. It reaches its At each beatv up of the lay a projection thereon (not shown) engages and lifts the hook end 134. This lowers the hook into its housing 136. Before the completed blue stripe has passed completely into the temple slot the threads B runs from the selvage to the idle shuttle in front of the hook 130. But since the hook is depressed at each beat up of the lay this idle thread B can -be freely advanced with the cloth and soon reaches a position where the hook, whenv it rises, on'the retreat of the lay, comes up at the rear of the thread. This stage of the formation of the slack in the selvage loops is illustrated in Fig. 1. As the thread B is drawn forward by the advance of the cloth it passes under a sprin pressed presser foot 138 '(see Figs. 3 and 5) coated on the tem le head just in advance of the hook 130. T is presser foot is ided by a stem 140, and serves to maintain the idle thread taut, as is shown by the-dotted line B in Fi 5. Now, when the blue color is to be use again, its shuttle box is brought down into weaving position and at the first pick of th'e blue thread through the shed it is drawn taut around the hook 130, as shown by the full line B in Fig. 5. Thus the hook revents the blue thread, at this first pick, om being drawn tightly to the selvage as isthe present practice, but on the otherhand insures the formation of the slack loop illustrated in Fig. 5. The next beat up of the lay withdraws the hook from the 100 so that it may advance freely with the 0 0th. The slack thus produced is utilized in severing the loops in the manner hereinbefore described. It will, of course, be understood that at each succeeding pick the blue thread is drawn in tightly to the .selva e and the hook does not again produce slac until the first pick of thewhite thread after the blue stripe has been completed.

It becomes necessary, at times, to pick out i a portion of the weft threads by hand, he-

cause of some imperfection or for other reasons, and at such times the temple head must be held in its forward positlon. To provide for this the temple shank 16 is provided intermediate its ends with a bore 150 (Fig. 2), and a sliding looking-pin 152 having a head 154 is carried in a horizontal housing 156 on the forward end of the templestand. On moving the temple head forward, by hand, to. a position where the bore 150 registers withthe pin 152, the pin can be shot into the bore and thus lock the temple head against return movement until it is desired to again continue the weaving operation, when the pin 150 is withdrawn.

Those familiar with the art of weaving blankets and the like, having striped end borders or woven throughout with different colored stripes of, the same or varying width according to the character of the design,

"will understand that the formation of complete box end-selvage loops depends upon Whether the width of any stripe or portion of one color, is less than the distance from the fell to the trimming device located forward thereof. As illustrated, a' striped blanket is being produced of a design permitting five alternating white and blue stripes to be woven before the first of these five stripes is brought to the trimmer by the advance of the cloth through the loom. Accordingly the box changing mechanism operates five times and produces five complete loops from the inactive filling threads before the first of these loops is severed. A complete loop, i. e., attached to the selvage by both ends, will be formed at each box 0 anging operation provided the width of the stripe just woven is less than the distance from the fell to the trimmin device.

Assuming now that a blanket is being woven of such design that the stripes are wider than the distance from the fell to the trimming device then the advance of the cloth will bring the forward, selvage-attached end of the loop to the trimming device before a box changing operation occurs and while the rear end of the 100 still is on the bobbin in the idle shuttle. his condition would also occur when a blanket is being woven having a border of varicolored stripes and a central, or main portion of one color. In weaving such a design the inactive filling thread formin the lastwoven colored border-stri e won (1, in the absence of a trimmin device, continue to be drawn-from the bob in of the idle shuttle during the whole of the weaving of the long central portion of .the blanket. This bobbin loop-end would not be attached to the selvage until the next box changing operation to start weaving the succeeding border portion.

The present invention provides for severing the forward or selva e-attached end of. all inactive filling threa s that if left unsevered eventually would form complete .loops across portions of the cloth of one holds the portion thereof forward of the foot in a taut condition but still permitting it to be drawn from the bobbin of the idle shuttle while the forward movement of the cloth is advancing the selvage-attached end to the trimmer. Its yielding pressure also permits the spreader 94 to efi'ectually function to draw said attached end normal to the selvage edge inthe same manner as described for the shorter selvage loops. After severance of the forward end of such a loop no more thread is drawnfrom the bobbin of. the idle shuttle until the next box changing operation, the severed inactive thread from that bobbin remaining under control of the presser foot 138 until it again becomes active. After the boxes are changed the loose end produced by the previoustrimming operation, and now attached to the selvage, is advanced with the cloth, acted on by the spreader 94 and finally Severed. In ractice the trimmer may conveniently be a ut six or seven inches forward of the temple so that the loose end would approximate that length and any excess of the width of the stripe thereover will. be a clear saving of filling thread yarn.

It will beunderstood from the foregoing description that my novel spreader 94 will function to extend, for proper presentation to the trimmer, any loose thread ends attached to the box end selvage however they may have been formed, causing the loom to produce cloth requiring no further trimming of that selvage edge. Furthermore, since the selvage gage 25 maintains the selvage gage 25 maintains the selvage edge spaced from the field of operation of the cutters, all danger of injuring the cloth at any filling thread trimming operation is wholly eliminated.

. That my temple selvage trimmer is accurate and eflicient in operation will be apgarent from the foregoing description. utting mechanism in a vertical plane cannot be employed, without danger of in'ury to the cloth, unless means is provide to produce slack in the selvage loops, and those skilled in the art will reco ize that it is not possible to trim these 00 s, when tight, with a knife operating in t e plane of the cloth. The movement of the movable cutting blademay be effected from any moving part of the loom, and the invention is not limited to a control from the temple.

\Vhile the novel features of the invention are best adapted for use in a box loom, those skilled in the art will recognize that some features described are useful in other kinds of looms. The various features of my invention, therefore, are not limited to use in combination with each other, or to use in a box loom, wherever it is clear that the ad vantages claimed for the invention may be obtained. from other combinations or other applications of its underlying principles.

It will be clear to those skilled in the textile art, and with the general; objects of the present invention-in view, that changes'may be made in the details of structure, the described and illustrated embodiment of the invention being intended as an exploitation of its underlying essentials, the features whereof are definitely stated in their true scope in the claims herewith.

39. In a box loom of the type having box changing and cloth advancing mechanism, temples, a presser foot within the slot of the box end temple and in the path of the filling thread running from the selvage to the bobbin of an idle shuttle, means for causin said presser foot yieldingly to clamp said lling thread whereby the run of said thread from its attachment to the selvage to said presser foot is held taut but is permitted to draw from its bobbin as the cloth is advanced, and automatic means for severing said filling thread before the cloth leaves the loom.

40. In a box loom of the type having box changing and cloth advancing mechanism, temples, a yielding presser foot adjacent the selvage and outside the tem 1e roll of the box end temple adapted to ear upon the filling thread runnin to the cloth from an idle shuttle, and filing thread severing means located'in the ath of said advancing thread and operated y'the loom.

41. In a box loom of the type having box changing and cloth advancing mechanism, temples, a yielding presser foot adjacent the selvage and outside the temple roll of the box end temple adapted to hold all inactive filling threads away from the selvage while another filling thread is being picked through the shed, and a cutter forward of v the temple operating successively upon said threads as they are advanced by the moving cloth.

42. In a box loom, temples, and a yielding presser foot outside the temple roll of the box end temple operating automatically to vcontinuously ress upon and hold in inactive position all fi ling threads, that are attached to the selvage at one end, which are not being used to-weave additional cloth.

43. In a box loom of the type adapted to produce adjacent stripes having different characteristics, a filling thread cutter forward of the temple at the box end of thesaid threads from the cloth while'still connected to said bobbins.

44, In a box loom, means at the box end of the loom for holding waste filling threads in substantially the plane of the cloth, a device movable to draw the end portions of said threads outwardly from the selva e across said means into a osition generalIy normal tot-he selvage e ge, a cutter, and means for feeding said threads from said device and past the cutter to be severed thereby.

45. In a box loom, a hook outside the selvage at the box end and opposite the. tell but in advance of the path of active shuttles through the shed, means for withdrawing said hook after a change of color to permit the just active but now idle filling thread to pass from its rear side to its forward side, and means for maintaining said hook in operative position on the first pick of said filling thread when its shuttle again becomes active,whereby the hook prevents said thread on said first ick after each change of color from being rawn taut to the selvage and produces a slack selvage loop. 7

46. In a box loom, automatic means for increasing the length of the filling thread which is to form a loop on the box end selvage and extending from a stripe of one color across the intervening cloth to the next stripe of the same color, and automatic means for severing said loop from. the selvage.

spreading said slack loops, and for severing said spread loops.

48. In a box loom, means adjacent the fell at the box end of the loom for engaging the 19 filling thread leading to an idle shuttle and forming a slack salvage loop on the first pick when said shuttle becomes active whereupon said means becomes inoperative until the next box changing operation, and means forward of the fell for severing said slack loops.

49. In a box loom, a member mounted on the temple at the box and of the loom, outside the edge of the cloth but inside the fillingthread leading to an idle shuttle, adapted to be engaged by said thread on the first pick when said shuttle becomes active where by to form a slack salvage loop, means to release said loop from said member before the next succeeding pick of said shuttle, and means for severing said slack loop from the salvage.

50. In a box loom, means at the fell for producing slack in the filling thread loops attached to the box end selvage, means forward of the fell for severing said 100 s, and actuating means therefor controlled y the operation of the loom.
